Trade dollars were once used as a form of currency in international trade, particularly in Asia. These coins, minted in the late 1800s and early 1900s, had a distinct design and were often made of silver. While "trade dollar" is the most commonly used term to refer to these coins, there are other synonyms that are also used. These include "Commercial dollar," "Chinese dollar," "Oriental dollar," and "Flowing Hair dollar." Each name reflects the coin's use and design, as well as its place in history. Today, trade dollars are highly sought after by collectors and investors alike, both for their historical significance and as a tangible investment.
